研究目的:

1.主要目标:评价基于 3D 打印模型的剥除顺序规划对术中出血量和手术时间的影响。 2.次要目标:比较干预组与对照组在缝合时间、并发症发生率、住院时长、术者主观负荷、患者沟通满意度等方面的差异。  

Objectives of Study:

1. Primary objective: To evaluate the impact of resection sequence planning based on 3D-printed models on intraoperative blood loss and surgical duration. 2. Secondary objectives: To compare differences between the intervention and control groups in terms of suturing time, complication rate, length of hospital stay, surgeon subjective workload, and patient communication satisfaction.
